, MANIFOLDING ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented June 22, 1M5.

To all whom it may concern Be it known that vnmm and LEOPOLD RAUH, citizens of the United States, residing atiDayton, in the countypf Montgomery and State of Ohio, have mvented certain new and useful Improvements in Manifolding Attachments for Type-VVriters, of which the followlngls a specification, reference being had therein to the accompanying drawing.

This invention relates to manifolding attachments for typewriters, of that type in which one or more webs of paper are fed from rolls, supported in the rear of the typewriter, through a series of ribbons supported by special ribbon-carrying devices and interposed between the usual typewriter ribbon and the platen.

The object of the present invention is to provide a ribbon carrying frame, to support a manifolding ribbon in proper relation to the platen of the typewriter carriage, which can be readily applied to a typewriter carriage without modification of the latter.

A further object is to so construct this supporting frame that it can be quickly and easily connected with the typewriter carriage without the use of tools or skill on the part of the operator, and to this end it is also an object of the invention to so construct the frame that it will slip onto a fixed part of the typewriter carriage and will be movably supported thereby, to permit the ribbons to be moved into and out of their operative positions; and to provide the frame with means for locking the same.

against movement relatively to the typewriter carriage when the ribbon is 1n operative relation to the platen.

It is also an object of the invention to provide this supporting frame with ribbon feeding devices which will be of such a character and so arranged that when the frame is in a position to support the ribbon in operative relation to the platen, the ribbon feeding devices will be arranged in operative relation to an operable part of the type writer carriage, preferably the line spacing mechanism. And a further object is toprovide a mechanism of this kind whlch w1ll bevery simple in its construction and opera- 'tion and of a very light construction, thus adding little to the weight of the typewriter carriage and making no appreciable difference' in the operation thereof.

In the accompanying drawings Figure 1 is a plan view of a typewriter showing the complete manifolding attachment connected therewith; Fig. 2 is an end elevation of the attachment showing the same in place; Fig.

3 is a transverse, sectional view taken just inside one of the end plates of the attachment; Fig. 4 is an elevation of that end of the attachment opposite the end shown in Fig. 2; and Fig. 5 is a detail view of one of the ribbon guides with the ribbon applied thereto.

In these drawings we have illustrated one embodiment of our invention and have shown the same designed for attachment to the No. 10 Remington typewriter, but it will be understood that the device can, by obvious modifications, be adapted for use in connection with various other typewriters.

In these drawings we have indicated the typewriter as a whole by the reference-nu meral l. Mounted upon the typewriter is the usual typewriter carriage 2 in which is journaled a platen 3. Suitable line spacing mechanism is connected with the platen to feedthe paper forward line by line as'the wrltlng progresses, and this mechanism, as embodied in this particular type of machine, comprises a lever 4 operatively connected by means of a crank arm 5 and a connecting rod 6 with a pawl 7 which is capable of bod ily movement and is preferably carried by a stud 8 mounted on a rock arm 9. This pawl is adapted to engage a ratchet wheel 10 secured to the end of the platen and to rotate the platen to advance the paper when the lever 4 is actuated.

The. usual typewriter ribbon is indicated at 11 and is supported and operated as usual.

The whole mechanism so far described is apart of the standard Remington typewriter, and no change whatever is made in this typewriter when the invention is ap plied thereto.

Mounted in the rear of the typewriter is a paper carrier consisting of a frame 12 mounted to travel along tracks 13, carried by a base 14:, and connected with the typewriter carriage by means of a connecting rod 15 so as to cause the frame 12 to move with the paper carriage.

Mounted on the frame 12 are a plurality of rolls of paper 16. The paper from the several rolls iscarried across the paper carriage of the typewriter where it is inter-' leaved between special ribbons which are interposed between the typewriter ribbon 11 and the platen 3.

The paper carrier and the means of connecting the same with the typewriter carriage do not form a part of the present invention, but are fully illustrated and-described in an application for patent filed by Messrs. ,M a ln 1 Rauh and Aker, July th, 1914., Ser. No. 852,024.

' nected by a flat bar 19 which serves as a paper support and guide, and the ribbon guides are in the form of angle plates 20 secured to the bar 19 at points near the opposite ends thereof and extending downward so that when the supporting frame is in its operative position on the carriage these ribbon guides will be located in a plane just in front of the platen. In this position the ribbon as shown at 21, w ich extends over and between the ribbon guides will extend for substantially the full length of the platen and will lie between the platen and the typewriter ribbon 11. These guide plates may be of' any suitablecharacter andtheir specific construction does not form a part of the present invention. Those here shown are so constructed that they will support the ribbon in three folds or plies, arranged one in front of the other so as to provide'three copies of the matter written, in addition to the copy produced by the typewriter ribbon. The ribbon is carnied by two reels or spools 22 mounted on opposite ends of a shaft 23, journaled in the end members 17 of the supporting frame. The ribbon is fed lengthwise over .the guides by winding it from one reel to the other. This reeling of the ribbon may be accomplished in various ways. In the present instance the reels are loosely mounted on the shaft 23 and are provided with clutch devices for separately connecting them therewith. As here shown, these clutch devices comprise pins 24 mounted in sleeves or elongated bearings 25 secured to the shaft 23, and adapted to enter recesses or holes in the adjacent faces of the respective reels, thereby connecting the reels to the shaft.

In the normal operation of the device one reel is clutched to the shaft so as to rotate therewith and wind the ribbon onto the same, while the other reel is loose on the shaft to permit it to rotate in the opposite direction and allow the ribbon to be unwound therefrom. To permit of this action, the bearings 25 are slotted as shown at 26 andthe pins 24 are provided with projections or small pins 27 adapted to enter the slots 26 when the pins are in their operative positions, and to engage the ends of the bearing sleeves to hold the pins. in their inoperative positions. The shaft 23 may be rotated to feed the paper in any suitable manner, but this is preferably accomplished by establishing an operative connection between the shaft and the line spacing mech-. anism of the carriage.

'As here shown, the end of the shaft is provided with a rat chet wheel 28 which is rigidly secured thereto, and an arm 29 is journaled on the end of the shaft adjacent to the ratchet wheel and carries a pawl 30 which is adapted to engage the teeth of theratchet and rotatethe shaft when the arm 29. is rocked about its axis. Thisarm 29 is connected, preferablyby means of a link 31, witha leyer 32, which is pivotally mounted on the frame member and has one end arranged-in the path of and adapted to be operated by al part of the line spacing mechanism. As here shown, this arm extends mto the ath of the stud 8 which carries the pawl 7 or actuating the platen, and, upon each movement of thepawl 7 the lever 32 willbe operated to actuate the shaft 23. This arra l'gement of the ribbon feeding devices enab es an operative connection to be established between the same and the line spacing, mechanism by merely placing the supporting frame in position upon the typewriter carriage. There is no positive connection between the two mechanisms, but their arrangement is such that the operation of the one causes the operation of the other.

A spring 33 is connected with the lever 32 to retract the pawl 29 after each operation thereof. -It is alsodesirable to provide the shaft 23 with a handle, as shown at 34, by means of which the ribbon reels may be actuated, as this materially facilitates the winding of a new ribbon on the spools and the threading of the same through the guides.

As has been stated, the frame is of such a character that it can be placed in position on the typewriter frame and clamped thereto without the use of tools or the exercise of skill on the part of the operator. Preferably, the end members 17 are so constructed that they will slip over or engage a part of the tylpewrit'er carriage and will thus support t e frame thereon. In the present in stance, the frame members 17 are provided 7 in the lower portions of their rear edges with inclined slots 35 which are adapted to extend over a part of the typewriter carriage and to ivotally support the frame thereon. In t e present instance, the typewriter carriage is provided with a rod 36, which is normally employed to support the paper shield and 'name plate, and this rod has been utilized as a support for the frame. It is usually fiat at its ends, and,'in the present instance, the slots 35 are formed of a width at their ends which will enable them to slip over these flat portions of the rod,

and are enlarged at their inner ends to permit the framemernbers to turn about the axis of the rod when they have been placed thereon. This construction, however, is not an essential one, although it is preferable that the slots should be arranged at an inclination to the horizontal so that when the supporting frame is in its normal position they will hold the rear portion of the frame against vertical movement. After the slotted frame members have been placed in engagement with the rod on the typewriter carriage the frame is moved downward to its normal position, in which it supports the ribbon in front of the platen, and is secured to the typewriter carriage in such a manner as to hold it against movement relatively thereto. Preferably, this means is finger-actuated so that no tools will be required in connecting the attachment, and, it is here shown as comprising a finger-operated catch 37 pivoted to one of the frame members 17 and adapted to engage the shaft of the platen on the typewriter carriage. The construction of the catch and its position with relation to the shaft is such that when moved into engagement-with the shaft it will clamp the frame firmly to the carriage. It will be noted that this arrangement is such that ivotal movement may be imparted to the rame, without detaching the same from the carriage, to elevate the ribbon guides and ribbon and place the same in a positionwhere they will be readily accessible either to thread the ribbon through the guides or to thread the paper through the ribbons.

The operation of the device will be readily understood from the foregoing description thereof, and it will be noted that to attach the device to the typewriter it is only necessary to place the slotted frame members in engagement with the rod on' the typewriter carriage, move the frame forward to its normal or horizontal position and manipulate the finger catch 34: to clamp the frame in this position. I

The device is exceedingly simple, comprising very few parts, and these parts are of a simple character. Further, the parts are of such a character that they are very light of.

weight and add little to the weight of the by Letters Patent,'is:

typewriter carriage,- and, consequently, make .no appreciable difference in the operation riage, is placed in position in the'rear of the machine and the webs of paper from the rolls on said support are carried over the carriage and supporting frame and are threaded through the supplemental ribbo as hereinbefore described.

The paper and the paper carrier are supported independently of the typewriter frame and carriage so as to impose no strain thereon.
